Hello,
I established a connection between my central and peripheral module. Now i want to write characteristic value on peripheral. I tried with sd_ble_gattc_write function...
I am using the NRF24l01 for my products and looking to buy in bulk(100-1000). Now I know where to buy the just the IC but antenna design is a hard point to break right now...
Hi, my friend,
I've been with nrf905. I use a 16-bit CRC check.
But I encountered problems in use:
1.Nrf905 16-bit CRC check format is CRC-16(IBM):X16+X15+X2+1 or other...
I have two custom PCBs, each of which has a microcontroller and an nrf24L01+. Everything related to the transceiver in the designs are complete duplicates (with the exception...
Hello,

Hi there~. I tried Nordic's FFT example (SDK 14.2) with a PCA10040 board. So I tried to add that FFT related codes in the heart rate peripheral example. I use the Segger's...
Hello, I am practising and studying the beacon example on nrf52840. While reading the main code, I try to delete the log_init part, however the kit doesn't advertise. I am...
Hello, I hope to realise a scenario that, my kit(nrf52840) advertises certain information, all the mobiles nearby (with BLE) could receive the information. I think the non_connectable...
Hi,
I'm looking for mBed OS 5 examples I can run on the nRF52-DK. At the mBed GitHub, I only found a Blinky and a BLE sample. I'm wondering if you are familiar with more...
I can see that there is one example for UART and it uses application uart module (APP_UART_FIFO_INIT ...). I used this module for printing strings on terminal window, but...
Hello,
I have been working with a nrf52DK PCA10040 V1.2.1 on SDK 14 without a softdevice and I have encountered a problem with a TWI sensor.
I have a TE MEAS MS5611...
Hello,
my usecase is the following: I'd like to use SoftDevice for BLE Advertising / Scanning - every now and then I'd like to "pause" BLE for a few miliseconds and send...
I download the demo project \nRF51_SDK_8.0.0_5fc2c3a\examples\peripheral\uart\uart.uvmpw to my nRF51-DK board, but uart didn't work,all 4 LEDs are on. Is there any mistake...
Finally, I managed to compile ble_beacon in segger.
However, here's what I can not understand.
Using either Segger -> Target -> Download File
or RKNRFGO I managed to...
I got beacon which use nRF51822.
I need to get radiated pattern diagram as attached picture.
this is to get KC certificate.
How can I get information? beacon maker...
Hello,
I'm using a module based on the nRF52810, the Fanstel BT832A. I'm running the basic "ble_app_beacon" firmware from the "nRF5_SDK_14.2.0_17b948a" SDK with a few changes...
I spent a few hours trying to change the base UUID and handles of the attributes of the Blinky peripheral app, just the one service and the button and LED characteristics...
I have couple of nRF51422 boards, nRF5-SDK-for-Mesh (v. 1.0.0) and good will to demonstrate some simple multihop mesh.
And I want to write some data to the flash, but operating...
